I am seeking a patient and knowledgeable chemistry tutor to help my teenage child improve their understanding of key concepts in high school chemistry. We need assistance with topics like chemical reactions, stoichiometry, and periodic table trends. Ideally, the tutor should be able to explain things clearly and provide practice problems. Sessions would be once or twice a week, preferably in the afternoons or early evenings. We are located near Dublin and would prefer someone who can either come to our home or offer online lessons.
